Spring is here…

Which must mean it’s time for messing around with some infrareds on a warm sunny day….

Sony RX100 Infrared R72 filter

Everything still works as it should! Black skies and water, white vegetation and clouds.

It’s good to see the IR effect again after a long wet winter. Fresh foliage seems to reflect more IR wavelength light than older grass and leaves so the ‘Wood Effect‘ is especially pronounced.

Sony RX100 Infrared R72 filter

Here’s the setup – an RX100 with R72 filter held on a Lensmate filter attachment. A much better arrangement than just holding the filter over the lens, this little gadget is very useful. The AG-R1 grip is also attached and transforms the RX100’s handling (get one!).

All shot at the ’28mm’ focal length (really 10.4mm) at f2, ISO 800 with a +1 stop exposure compensation to allow hand held speeds of between 1/30th of a second and 1/8th of a second. These were processed in DXO Optics Pro 9 using the ‘Dense’ black and white conversion – straight from the camera they have a very intense magenta hue. A slight ‘diffuse glow’ was added in Photoshop to give it that old Kodak IR film look.

A bit more abstract here – fresh growth in a pond with some clouds reflected.

Same bridge – but from the other side.

More of a traditional landscape really – the vegetation at the lower right seems to be ‘reaching into’ the frame.

Not a bad result for some gentle messing about – more a practice for later in the year.

Last Few Weeks

Not many posts over the last few weeks as I’ve been completely absorbed in planning a complex time lapse video project. Some stills have been taken despite recent developments, so here are the best ones, though it’s a pretty random selection!

First – a plastic lensbaby shot of some fresh leaves with the sunlight edging in from behind. The flare, sharpness and chromatic aberration are terrible by conventional standards, but working with a lensbaby is primarily about finding shooting situations where that doesn’t matter.

Next a Sony RX100 shot of a dumped TV in a pond on the nearby heathland. This is very unusual as most people respect the area, but there are always those who don’t. The contrast between the disposable consumer goods dumped in an ancient landscape provided a striking contrast.

_DSC1014_DxOFP

This time a macro with the venerable 50mm f3.5 OM system lens mounted on extension tubes on a Canon 60D to get a really close focus. The subject is just a crow’s feather found in the garden – always a fascinating subject.

_MG_9783_DxOFP

Finally an off centre shot with the Helios 85mm f2 of a weathered ‘sculpture’ (can’t think of a better word) near a church door.

All pictures for the book cover market – as always. Hope you like them!

Compact Camera vs DSLR – a silly comparison?

Most keen photographers have always faced a dilemma – their DSLR (or SLR for those who still use film) and standard zoom produce very good results, but carrying one all the time is a pain and opportunities are everywhere! A small camera is the solution, but small digital cameras are usually compromised by limited ISO performance, they’re not often that small and even their best results aren’t as good – at least that’s what I’ve found having used several (small film cameras are a different matter). A test is in order…

So to see if things have changed here’s a test between a two-year old mid range DSLR with an upgraded kit lens against a new top of the range compact. Not a fair test on the surface, but who said anything about fair? The differences in size and weight are obvious but the results are a bit of a surprise….

camerashots

The APSC sensor format Canon 60D with interchangeable EF-S 15-85mm (24-135mm equiv) lens on the left, Sony RX100 with smaller one inch sensor on the right with a fixed 28-100mm lens. The 60D boasts 18Mp, the RX100 20Mp – a negligible difference in practice.

The Canon has been used consistently for over two years, and has never failed to impress over ten thousand images with a wide variety of lenses. The Sony is relatively new (three months)  but is up to 1000 shots already. It’s images are more ‘consumer’ oriented with brighter colours and what looks like more sharpening, but very good nevertheless.
The Sony’s lens is a bright f1.8 to f4.9 across it’s zoom range, the 15-85mm a more modest f3.5 to f5.6. I’ve no complaints about the handling of either camera, neither having any irritating quirks which would drive you mad. My personal choice for useable maximum ISO is 800 on the RX100 but the Canon can be pushed further to 3200 in an emergency.

The Sony is doing a lot of processing to work around the design compromises of fitting such a tiny fast lens into a small body. Here’s a close up (ish) wide angle image with distortion correction on and off (done in the Sony Raw converter). Although the correction is done very well my initial thoughts would be that this much correction must result in poor edge performance – we’ll see! It’s worth stressing that this correction has to be explicitly switched off in the RAW converter to see this – you won’t see it on the camera’s replay function or in JPGs or RAWs by default.

_DSC0993_dc_comparison

Sony -distortion correction on and off

The main ‘problem’ with the Sony is the colour rendition – reds, greens and yellows are all a bit ‘off’ for my taste, but shooting in RAW and using a correcting colour profiles in ACR (see Maurizio Piraccini’s website here) fixes the problem to give a more subtle result.

_DSC0998_colour_comparison

Corrected colour – here a red postbox, the corrected on the left and the straight RAW to JPG result on the right. DPReview found the same thing in their (much more scientific and exhaustive) test.

So – on to the mini test and it will be familiar to anyone who’s read the film and lens test from earlier in the year – there’s a lot more vegetation now though! All shots in RAW and converted to JPG using the supplier’s RAW converter. The Canon’s ISO setting was 100, the Sony’s 125 (it’s native ISO). I haven’t worried about colour here as it’s important to compare default outputs.

C_24_5.6_small

Wideangle on both lenses – the 15-85mm Canon is a bit wider than the Sony – 24mm vs 28mm, but not significant for these tests.

Starting at max aperture, this definitely a surprise and a significant difference. The Sony is producing very sharp results (it’s sharpening is at a higher level by default), and the edges which have been heavily ‘corrected’ aren’t bad at all.

C_24_f3.5_composite

Canon – 15mm setting f3.5. Centre and top right crops.

S_28_f1.8_composite

Sony 28mm setting f2. f1.8 would gave resulted in more overexposure.  Centre and top right crops.

At mid apertures things are much more even – mid apertures usually produce the best results in all lenses.

C_24_5.6composite

Canon – 15mm setting f5.6. Centre and top right crops.

S_28_f4.5_composite

Sony 28mm setting f4.5. Centre and top right crops.

On to approximately a 50mm setting :-

C_50_f5_small

C_50_f5composite

Canon at 50mm f5 (max aperture at this focal length) and excellent.

S_50_f4.9composite

Sony at around the same focal length (not exactly – hence the slightly different edge crop – apologies). This is good too!

Finally at tele setting – 135mm equiv on the Canon, 100mm on the Sony.

C_85_f8_small

C_85_f5.6composite

Canon at 85mm f5.6 (max aperture at this focal length) – bit soft at the edge but OK.

S_100_f7.1_composite

So definitely a surprise. I checked then double checked that the images were correctly attributed, but it was right first time! The little Sony is matching or even exceeding the Canon 15-85mm in terms of sharpness and detail, as well as having a wider maximum aperture. As I remember this lens alone cost as much as the compact camera!

The differences are probably down to the default sharpening parameters in the Sony, and highly polished image optimisation for a fixed zoom lens – the Canon can have hundreds of different lenses attached and can’t optimise images ‘in camera’ for all of them.

The Sony isn’t a replacement for the 60D – far from it. There’s no optical viewfinder for a start (composing on an LCD in bright sunshine is pure guesswork), the lens is fixed and the 60D’s sharpness and colour rendition is much more neutral and allow more latitude in post processing. Having said that, the RX100 is producing very impressive results without any work in terms of sharpness, and the ability to tweak the results in pp means that the gap between DSLR’s and compacts has definitely narrowed and I can use the RX100 with confidence in most situations.

Hope you find this useful – thanks for looking!

p.s I’m, not (unfortunately) sponsored by Canon or Sony – just using the cameras….

Yet More RX100 Infrareds!

Dorset is experiencing something weird this year – summer! The skies are clear, the temperatures are hitting 30 degrees C and for people used to cloudy wet summers with just a glimpse of sunshine now and then it’s all most disturbing…..

So using this hot weather as an excuse to shoot yet more infrared handheld on the unmodified RX100 (with an R72 filter) , here we go.

First, a few of the pedestrian bridges over the River Stour near Tarrant Crawford – the leaves and grasses radiating IR like mad. All taken at 28mm setting at f1.8 using RAW, the ‘Black and White’ creative setting (for composition) and +1 exposure compensation.

_DSC0950_DxOFP

This is the next bridge along – the field boundary is heavily overgrown on either side which help isolate the dark path.

_DSC0945_DxOFP

And the same view but in landscape orientation with a lower contrast – can’t make my mind up which of the two is best. _DSC0948_DxOFP

Finally a small avenue of trees taken on the same day, the shadows on the road being an integral part of the composition.

_DSC0902_DxOFP

As usual, all taken for the book cover market – hope you like them!

Abandoned Military Installation

Here’s a few more from a day on Portland (Dorset UK). These abandoned buildings are part of a Victorian artillery battery built on the island and abandoned decades ago. The subject was perfect for a drop more IR on the Sony RX100 (what a surprise) – so here we go. All shot at the 28mm setting at f1.8 handheld – the camera is unmodified.

This is a view down one of what I suppose was the tracks which brought ammunition from the stores to the gun positions – the concrete walkway over the rails is unexpected…

_DSC0750_DxOFP

Portland is great for this sort of shot – the island was heavily used by the military then handed over to prison services and much of that dark architecture remains. Can’t resist barbed wire!

_DSC0764_DxOFP

Back to the main fortification and some overgrown steps leading out of the depression in the ground which houses the gun position. _DSC0763_DxOFP

Finally a view of some of what I suppose were store houses, the sparse grassy vegetation slowly growing over the banks and stone. _DSC0754_DxOFP

Altogether a wonderful spot – and good weather for IR photography. The R72 filter has got to be left at home for a while now. That and the plastic Lensbaby are taking up too much time!

Thanks for looking – hope you like them.

Infrared on Portland (Dorset)

A few infrareds from a great day in Weymouth and Portland in superb sunny weather. All taken on using the Sony RX100 and R72 filter, post processed in DXO to tweak the contrast.

This cemetery has some of the best monuments in the area – and a great subject for IR against a clear blue sky with some high cloud to give some texture. These are two of the most impressive.

_DSC0779_DxOFP

This is the first statue complete with broken wing from the rear – the bright dot in the sky is flare from the lens. The RX100 produces some very complex flare (see later article).

_DSC0780_DxOFP

Finally a closer view of another monument. This camera produces very high IR quality images. better than my old IR digital camera, a Fuji F810.

Another Good Day for Infrared…

Been up on the chalk downland again – and wide open spaces in the sunshine have to mean one thing, Infrared.  All hand-held using the Sony RX100 + R72 filter and heavily post-processsing in Photoshop and DXO.

The conditions were perfect – light broken cloud and strong sunshine which means some texture in the sky an a strong infrared response.

This is the remains of an old field boundary – these thorn bushes are all that’s left in an otherwise empty landscape.

_DSC0710_DxOFPs

This road is beautifully straight. running along a long shallow valley. I did a few of this as the contrast between the tarmac and the ir-reflecting vegetation was very strong.

_DSC0692_DxOFPs

Slightly different post-processing on this one to allow the whites of the grass to burn out a little – usually a sin but worked out well for this one.

_DSC0703_DxOFPs

Finally one in a favoutite location, where the clear chalk stream turns a bend, and a line of poplar trees makes a nice background.
